Description

Oct. 11, 1955 SCHEITERLEIN ARRANGEMENT FOR INTERNAL-COMBUSTION ENGINES Filed DEC. 29, 1952 United States Patent ARRANGEMENT FOR INTERNAL-COMBUSTION ENGINES Andreas Scheiterlein, Graz, Austria, assignor to Gustav Ospelt, Vaduz, Liechtenstein Application December 29, 1952, Serial No. 328,381
Claims. (Cl. 123-495) The invention relates to an arrangement of a cooling water pump and a dynamo for internal-combustion engines, in which the cooling water pump and the dynamo are coaxial and driven jointly. Such coaxial arrangements of a cooling water pump and a dynamo with a joint drive are known in internal-combustion engines and afford the advantage of a better utilization of space and of a simplification of the drive. In those known arrangements the cooling water pump and the dynamo are separately mounted to the engine housing. In particular in constructions in which the impeller of the water pump is arranged on the shaft stub of the dynamo, that arrangement involves difiiculties in assembly. In such constructions the accurate adjustment of the clearance between the impeller and pump casing, which adjustment is controlling for the efiiciency of the water pump, is complicated and time consuming because that adjustment must be effected during the assembly of the units with the engine.
The invention has as its object to eliminate these disadvantages and essentially resides in the fact that the casing of the cooling water pump and the support for the dynamo are connected suitably by a common or joint baseplate, to form a unit that can be attached to the internal-combustion engine, to enable a joint machining of the casing of the pump and of the support of the dynamo. The joint machining of the casing of the water pump and of the support for the dynamo, which machining can then be effected conveniently with the same chucking, ensures accurate alignment of the casing axis with the axis of the dynamo. Now the unit can be assembled easily and in a simple manner independently of its attachment to the engine Without requiring a special adjustment. Particularly in the case of arrangements in which the impeller of the water pump is mounted directly on a shaft stub of the dynamo, the advantage results that the proper setting of the impeller relative to the casing is ensured. In that case the casing of the cooling water pump, the support for the dynamo and the common or joint baseplate, if provided, suitably consist of a single casting, to simplify the manufacture.
In the drawing the invention is illustrated diagrammatically with reference to an example.
Fig. 1 is a top plan view of the unit consisting of the dynamo and the cooling water pump, the latter being shown in axial section.
Fig. 2 is a top plan view of the pump casing and the support for the dynamo.
Fig. 3 is a sectional view taken along line III-III of Fig. 1, and
Fig. 4 is a sectional view taken along line IV-IV of Fig. 1.
The impeller 1 of the cooling water pump is located by means of a screw cap 4 on the shaft stub 2 of the dynamo 3 and rotates within the pump casing 5 designed as a volute casing. The suction bend 6 is fixed to the pump casing by means of screws 7. The clearance 8 between the impeller 1 and the suction bend 6 must be adjusted most accurately to obtain a high efliciency. 9 is the support for the dynamo 3 and is formed with a fiat curved depression according to the shape of the casing of the dynamo.
The pump casing 5 is connected to the support 9 through the intermediary of a baseplate 10. As shown by the example given in the drawing, the casing 5 forms a single casting with the support 9 and the baseplate 10. The dynamo 3 is located on its support by means of a bail 11, which is tightened by screws 12 screwed to the support 9. The supporting surface of the support 9 and the casing 5 having been machined jointly, accurate alignment of the axis of the dynamo with the casing axis is ensured and no difficulties will be encountered in the assembly of the unit consisting of the dynamo and water pump. By means of the common or joint baseplate 10, that unit can be located at the engine housing 13 by means of screws 14. As shown in Fig. 3 of the drawing, the engine housing is formed with a sealing surface 15, to which the discharge branch 16 of the cooling water pump is connected so that the water outlet of the pump and the inlet to the engine extends directly through the common baseplate 10, which also has a sealing surface cooperating with the sealing surface 15.
I claim:
1. In an assembly principally for internal combustion engines the combination comprising a base plate; supporting means carried by the plate, a dynamo axially adjustably supported by the supporting means and including a shaft, a rotary cooling water pump including a casing secured to the plate coaxially with the dynamo and enclosing a shaft end portion and including an impeller wheel within the casing secured to the shaft end portion and means securing the dynamo in a predetermined axial position on the supporting means.
2. The combination according to claim 1 and also comprising a suction pipe detachably mounted on the casing and closing an opening through which the impeller wheel can be inserted for securement to the shaft and wherein the impeller wheel is adjustably secured to the shaft by a screw cap.
3. The combination according to claim 1 and also comprising an engine housing having a hole and a sealing surface adjacent to the hole and wherein the base plate has a sealing surface coacting with the first mentioned sealing surface and the casing includes a delivery conduit registering with the hole.
4. The combination according to claim 1 and wherein the supporting means has a trough-shaped depression and the securing means is a tensioning member attached to the supporting means.
5. The combination according to claim 4 and wherein the base plate, the supporting means and pump casing constitute a single casting.
